Check PercentRelativeLayout.

You can set percentage width in xml:

  app:layout_widthPercent="80%"

or in code:

PercentLayoutHelper.PercentLayoutParams params =(PercentLayoutHelper.PercentLayoutParams) view.getLayoutParams();
PercentLayoutHelper.PercentLayoutInfo info = params.getPercentLayoutInfo();
info.widthPercent = 80;
